The four LAUSD IHP critical thinking skills are the piece of the Mark Twain Middle School admissions process most families underestimate. They determine whether your child earns a qualifying score on the January assessment — and they are assessed from the moment your child's teacher submits a recommendation, not just on test day. I've seen students with strong grades and solid test scores fall short on the IHP Interdisciplinary Assessment simply because they trained for recall. This post names each of the four official skills LAUSD evaluators use, shows what each one looks like in practice, and gives you a concrete prep plan built around the actual criteria.

LAUSD Gifted Program Eligibility: Does Your Child Need GATE Identification to Apply for IHP?
No — GATE identification is one of three pathways into the IHP, not the only one. LAUSD accepts any of the following as proof of SAS eligibility:
- Active LAUSD Gifted designation (Intellectual Ability, High Achievement, Specific Academic, Creative, or Leadership Ability)
- Smarter Balanced Assessment (SBA) score of Standard Exceeded in both ELA and Math
- 85th national percentile or above on a District-approved norm-referenced test in both ELA and Math
Meeting one of those three criteria gets your child to the application stage. But eligibility alone does not earn a seat. Your child's current school must also verify the four critical thinking and problem-solving skills before the January assessment. That verification happens through teacher observations and recommendations — which means the skills need to show up in daily classroom work, not just on a single test day.
Two teacher recommendations are required: one from your child's ELA teacher and one from their Math teacher. Those teachers are not simply vouching for grades. They are specifically confirming that your child demonstrates each of the four LAUSD-defined critical thinking behaviors listed in the next section.
The Four LAUSD IHP Critical Thinking and Problem-Solving Skills — What Each One Actually Means
LAUSD's official IHP criteria name four specific skills that evaluators look for during the assessment and verify through the school of attendance. Here is exactly what each skill means and what it looks like when your child does it well.
Skill 1: Explaining Meanings and Relationships Among Facts with Depth and Complexity
This is not summarizing. Your child needs to connect ideas across concepts — explaining how a change in one variable in a science scenario causes a chain of effects, or linking a historical decision to its economic consequences. A surface-level answer names the fact. A depth-and-complexity answer explains why it matters and how it connects to something else.
Practice example: Ask your child to explain why the California Gold Rush affected population growth — then ask them to connect that to current LA demographics. Push for two or three logical links, not just one. If they can only name the fact without building the chain, that is the skill gap to close.
Skill 2: Formulating New Ideas and Elaborating Beyond What the Question Asks
IHP evaluators want to see original thinking — not a restatement of what a question already says. Your child should be able to take a concept, extend it, and propose something the prompt did not explicitly ask for. This shows up in open-ended problem-solving sections where a correct answer alone is not enough. Elaboration earns credit.
Practice example: After solving a math problem, ask your child: "What if the numbers changed? Would your method still work — and why?" Getting comfortable with that follow-up is exactly what the IHP open-ended format demands. From what I've seen, students who practice explaining their reasoning out loud handle this part of the exam far more confidently than those who only practice writing answers.
Skill 3: Using Alternative Methods to Solve Unfamiliar IHP Math Problems
This skill separates procedural memorizers from real mathematical thinkers. When your child sees a problem where the standard algorithm does not obviously apply, can they try a different approach? Draw a diagram? Work backwards? Use estimation to check whether an answer is reasonable?
The IHP Math section integrates Science content, so problems may involve unit conversion inside a physical science scenario, or data interpretation inside a life science context. Drilling only one method per problem type will leave your child stuck when the format shifts. I've found that students who practice solving the same problem two different ways — then explain which method is more efficient — build exactly the flexibility this section rewards.
Practice example: Present your child with a multi-step word problem and require them to solve it two different ways. Then ask which method was more efficient and why. That last question is the one the IHP actually cares about.
Skill 4: Using Extensive Vocabulary Accurately to Express Creative Ideas
Based on what LAUSD has publicly disclosed about the IHP format, there is no standalone essay section. But this skill runs through everything — especially open-ended problem-solving responses and the post-assessment interview. Evaluators are reading and listening for precise academic vocabulary used correctly. Vague answers like "it affects things" do not demonstrate this skill. Answers like "the disproportionate allocation of resources limits economic mobility" do.
What the IHP Interdisciplinary Assessment Tests — and Why GATE Critical Thinking Prep Is Different
The IHP Interdisciplinary Assessment is not the Smarter Balanced, not a GATE identification test, and not a traditional multiple-choice exam. It is specifically designed to verify that your child is performing two to three grade levels above peers. For a 5th grader entering 6th grade, that means content difficulty in the 7th-to-8th-grade range.
The four sections — Mathematics with Science content, ELA with History content, Critical Thinking, and Problem Solving — are intentionally integrated. A math question might embed a physics scenario. An ELA question might ask your child to evaluate a primary historical source. The format includes both multiple choice and open-ended problem solving, and exact question formats are not publicly disclosed by LAUSD.
Students who prepare only with grade-level Smarter Balanced practice often score below the qualifying threshold on the IHP assessment. The critical thinking and problem-solving sections require your child to reason through novel situations — not retrieve practiced answers. That is a different cognitive skill, and it takes specific practice to build.
How to Prep for LAUSD IHP Critical Thinking Skills: A Four-Phase Plan
Mark Twain publishes no official practice tests for the IHP Interdisciplinary Assessment. That means preparation requires building a practice plan around the skills the exam actually tests. Here is a realistic four-phase approach timed to the October-to-January window.
Phase 1 (October): Find Your Child's Weakest IHP Critical Thinking Skill
Run a simple diagnostic at home. Give your child an above-grade-level math problem and ask them to explain their solution in writing. Then give them a reading passage two grade levels above and ask for three sentences connecting the text to something else they already know. Review both responses for evidence of the four skills. The weakest one is where to spend the most October time.
Phase 2 (November): Targeted Practice on Each of the Four Skills
Spend one week per skill. For alternative math methods, pull problems from 7th and 8th-grade curricula — proportional reasoning, algebraic expressions, geometric measurement. For depth-and-complexity reasoning, use integrated science-history prompts that require multi-step analysis. For vocabulary expression, shift from written responses to verbal ones. The IHP interview requires your child to speak, not just write — so this transition matters.
Phase 3 (December): Integrated STEM Critical Thinking Practice Under Timed Conditions
Combine all four skill areas into timed sessions. Use STEM critical thinking practice tests that mirror the interdisciplinary format — math problems with applied science context, reading comprehension with analytical writing components. Practice explaining solutions aloud. That habit directly prepares your child for both the open-ended exam sections and the interview. See our STEM Critical Thinking Practice Tests for timed, IHP-format practice built around all four skills.
Phase 4 (January): Final Review and IHP Interview Readiness
Ease off new content. Run mock interviews at home — ask your child open-ended questions about books they've read, science topics they've studied, or hypothetical problems. Practice full-sentence answers with academic vocabulary. Have your child name and describe all four critical thinking skills out loud. If they can explain what each skill is and give an example, they are ready to demonstrate it in the room.
Mark Twain IHP vs. Walter Reed IHP: Key Differences for LAUSD Families
Both the Mark Twain IHP and the Walter Reed IHP use the same LAUSD SAS eligibility criteria and the same January assessment structure. The admissions process, qualifying requirements, and four critical thinking skills rubric are identical at both schools.
The differences are geographic and programmatic. Mark Twain MS is located in the Venice/Mar Vista area of Los Angeles. It also houses Mandarin Immersion and World Languages Magnet strands — but IHP students enroll in the IHP cohort specifically, and dual enrollment with a language magnet strand is not typically available. Walter Reed MS is in North Hollywood and serves a different geographic catchment area.
Lottery priority goes first to siblings, then to students within the school's LAUSD attendance boundary. If your address falls within Mark Twain's boundary, you have lottery priority there. If it falls within Walter Reed's boundary, you have priority there. Applying to both is permitted — and worth doing if your child qualifies.
I've seen families commute across LA to attend a school outside their boundary when a seat within their own boundary was available. Always check the LAUSD boundary locator before you finalize your Choices application.
Frequently Asked Questions: LAUSD IHP Critical Thinking Skills and Mark Twain Middle School IHP Admissions
Q: What are the four critical thinking skills LAUSD looks for in IHP applicants?
A: LAUSD evaluators look for four specific skills: (1) explaining meanings and relationships among facts with depth and complexity — for example, connecting a science concept to a historical event; (2) formulating new ideas and elaborating on them beyond what the question asks; (3) using alternative methods to solve unfamiliar math problems rather than relying on a single memorized procedure; and (4) using extensive vocabulary accurately to express creative ideas. Each skill is verified by your child's current school before the January assessment, and all four are directly assessed during the IHP Interdisciplinary Assessment itself.
Q: Can a student without GATE identification still qualify for the IHP?
A: Yes. LAUSD offers three eligibility pathways. Pathway one is an active GATE designation (Intellectual Ability, High Achievement, Specific Academic, Creative, or Leadership Ability). Pathway two is scoring Standard Exceeded on both the ELA and Math Smarter Balanced Assessment. Pathway three is scoring at or above the 85th national percentile on a District-approved norm-referenced test in both ELA and Math. Students who qualify through Pathway two or three — with no GATE label — can still apply, sit the January assessment, and earn a spot if their school verifies the four critical thinking skills and they score at the qualifying threshold.
Q: How is STEM critical thinking different from regular test prep for the IHP assessment?
A: Standard test prep drills isolated skills — grammar rules, multiplication facts, vocabulary lists. The IHP Interdisciplinary Assessment requires your child to reason across subjects at the same time: a math problem may carry a science context, and an ELA question may embed historical content. Evaluators are checking whether your child can apply reasoning to unfamiliar situations, not recall memorized answers. STEM critical thinking practice that uses open-ended, multi-step problems with integrated content domains is the closest available match to IHP-style question difficulty.
Q: What does performing two to three grade levels above peers actually look like on the IHP assessment?
A: A 5th grader applying for 6th-grade IHP entry would be expected to handle content difficulty typical of 7th-to-8th-grade coursework. In math, that means multi-step problems involving proportional reasoning, algebraic thinking, or geometric measurement — not single-operation arithmetic. In ELA, it means analyzing author's purpose, evaluating argument strength, and synthesizing information across two texts. The open-ended problem-solving section specifically rewards students who can explain their reasoning in writing with precise academic vocabulary, not just arrive at a correct numerical answer.
Q: What happens at the IHP interview, and how should my child prepare?
A: The interview runs approximately 15 minutes and has two parts: a student-only segment and a student-plus-parent segment. Interviewers are assessing whether your child can articulate complex ideas clearly, show intellectual curiosity, and explain their thinking process — not recite a rehearsed speech. Concrete preparation steps include: practicing explaining math solutions aloud step by step, discussing books or science topics in full sentences using academic vocabulary, and doing one or two mock conversations where a parent asks open-ended questions like "Why do you think that?" or "What would happen if the problem changed?"
Q: How competitive is the IHP at Mark Twain, and how many seats are available?
A: The 2026-27 6th-grade IHP cohort is limited to one class section — typically 28 to 32 students — which makes available seats extremely limited relative to the applicant pool in a district the size of LAUSD. When more qualified applicants than seats exist after the qualifying assessment threshold is met, LAUSD conducts a random unbiased lottery. Priority in that lottery follows this order: siblings within school boundaries, siblings within LAUSD boundaries, LAUSD-boundary applicants, and finally inter-district permit holders. No official acceptance rate is published, but the single-section cap means preparation that gets your child above the qualifying threshold — not just near it — is the most reliable strategy.
Q: What is the difference between the IHP at Mark Twain and the IHP at Walter Reed Middle School?
A: Both programs are LAUSD Individualized Honors Programs and share the same SAS eligibility criteria and January assessment structure. The key differences are geographic attendance boundaries, campus culture, and available co-curricular programs. Mark Twain MS is located in Venice/Mar Vista and is also home to Mandarin Immersion and World Languages Magnet strands. Walter Reed MS is in North Hollywood. If your child qualifies for both, the choice often comes down to which school falls within your LAUSD attendance boundary — boundary applicants receive lottery priority over inter-district permit holders at both campuses.
Q: If my child misses the November 14 Choices deadline, can they still apply to the IHP?
A: No. The LAUSD Choices on-time window for the 2026-27 school year closed November 14, 2025. Late Choices applications open February 2, 2026, but late IHP applicants are not invited to the January assessment. Missing the on-time deadline effectively means missing the entire IHP cycle for that school year. Mark Twain's in-house IHP application has historically had its own separate deadline in mid-to-late November — you must complete both the LAUSD Choices submission and the school's in-house application to be considered.
